Definitions

  • the present invention relates to a method of increasing the output power from photovoltaic cells with different known systems and of reducing to a minimum the temperature of photovoltaic cells, which negatively affects the voltage.
  • the mono-crystalline silicone by which the cells attain a yield of 23% and the units which produce from 10% to 14%.
  • the commercialization price of these units is in the range of US$ 5 to 6 perwaft.
  • the units of the semi-crystalline silicone formed a quarter of the international photovoltaic sales in 1988 and their production is between 12% and 13%.
  • the amorphous silicone has a weak production, which is about 7%, and because of that its production becomes expensive.
  • FIG. 4 illustrates that such loss is essentially due to a reduction of the voltage of short circuit.
  • the spectrum of the solar rays spreads into the ultraviolet passing through the visible and the infrared at distance.
  • the photovoltaic cells in general, are insensible to light outside the visible and the very near infrared. This characteristic is reflected in the FIG. 3 which mentions the response curve of a conventional photovoltaic cell.
  • the solar light emits energy in the bands of ultra violets and infrareds, and the band of the visible one as well.
  • h the constant of PLANK
  • c velocity of the light
  • ⁇ length of the wave.
  • Mode of concentration with multi prisms recalling physical data: consider 2 transparent mediums, M 1 and M 2 , having respectively as an index of refraction: n 1 and n 2 ( FIG. 1 ).
  • R′ 1 is directed to the photovoltaic cell.
  • the surface of the face F 1 will be calculated in a manner so that all the rays falling on the surface will be refracted to cover all the surface of the photovoltaic cell.
  • the photovoltaic cell will receive much of the sunshine which falls at the faces, certainly with consideration to absorption of some luminosity at a level of multi prisms as well as the cosines of the solar rays with the photovoltaic cell.
  • the system used to realize the procedure of the invention comprises prisms which are located on several adjacent surfaces forming angles there between, calculated in a manner that all the refracted light rays converge fully on the surface of the solar module.
  • Each face is consisted of a number of similar multi prisms.
  • the method of the invention allows to considerably increasing the power of the nominal output of the existent solar units.
